To convert synodic months to days: multiply by 29.53059. To convert to calendar months: multiply by ~0.970.
1 synodic month ≈ 29.53059 days ≈ 708.73 hours. Longer than a sidereal month (27.32 days) because Earth also moves in its orbit.
For example, 1 Month (Synodic) (mo (syn)) = 2551442976 Millisecond (ms).

The synodic month is the time between two successive new moons — approximately 29.53059 days (2,551,442.976 seconds).
1 synodic month ≈ 29.53059 days ≈ 708.73 hours. Longer than a sidereal month (27.32 days) because Earth also moves in its orbit.
To convert synodic months to days: multiply by 29.53059. To convert to calendar months: multiply by ~0.970.
Islamic calendar months, tidal cycle predictions, menstrual cycle correlations, and astronomical event planning.
The synodic month is ~2.2 days longer than the sidereal month because the Moon must 'catch up' to the same Sun-Earth-Moon alignment as Earth orbits.
Confusing synodic month with calendar month. The synodic month is ~29.5 days, shorter than most calendar months.
Watch the Moon for a full cycle from new moon to new moon — that's one synodic month (~29.5 days).
The millisecond is a unit of time equal to 10⁻³ seconds — one thousandth of a second.
1 ms = 0.001 s = 1,000 µs = 10⁶ ns. There are 1,000 milliseconds in one second.
To convert ms to seconds: divide by 1,000. To convert seconds to ms: multiply by 1,000.
Web page load times, video game frame timing (16.67 ms = 60 fps), network ping times, and heartbeat intervals (~800 ms).
Human reaction time to visual stimuli is about 250 ms. A housefly's wing beats once every 4 ms. A humming bird's wing: ~12 ms per beat.
Confusing ms (milliseconds) with Mb/s (megabits per second). In networking, ms measures latency while Mb/s measures throughput.
Your eye blink = ~300 ms. A 60 fps game = 16.67 ms per frame. These are great millisecond benchmarks.
